The AK34 is their Micro-ATX board and their AK74 line is their ATX boards. Branching off from their 74 series boards are the "SC, SU, and EC" models. The main differences between these three are the on-board audio and ATA-100 support. The SC model has AC97 on board sound, the SU has Creative On-Board sound, and the EC has AC97 on-board sound and ATA-100 support."
